In normal mode the Actor now writes an advisory record under the reserved KVS key TIP when the query or URL targets a site that has a dedicated Actor:

{ "message": "For scraping tiktok.com, we recommend using TikTok Scraper", "level": "info" }

Covers exactly the sites listed in the issue. Matches both plain URLs and domains mentioned in a search query (site:instagram.com nike).

Note: the record is stored after the crawl. Crawlee purges the default storages while the crawlers start up, so a write placed before that is silently lost.

Closes #141.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds the TIP_KVS_KEY constant and introduces site-specific ActorTip detection for supported domains, queries, and URLs. Query input takes precedence over URL input. Non-null tips are stored through Actor.setValue under TIP. Normal mode logs the tip before crawling and persists it after crawling, including before Actor.fail when crawling fails. Tests cover matching and persistence.

Merge Risk: 🟡 Moderate · up to 0d5c3

The change adds advisory TIP records, but failures while writing those records may mask crawl outcomes, and non-HTTP URI schemes may receive incorrect recommendations. The PR should not merge without addressing or explicitly accepting these bounded correctness and error-handling risks.

🚥 Pre-merge checks | ✅ 4
✅ Passed checks (4 passed)
Check name Status Explanation
Title check ✅ Passed The title clearly summarizes the main change: writing specialized Actor recommendations under the TIP key.
Description check ✅ Passed The description accurately describes TIP records, matching behavior, storage timing, and the linked issue.
Linked Issues check ✅ Passed The implementation adds the reserved TIP key, stores a single message and level record, recommends the sites listed in issue #141, supports URL and query matching, and avoids platform changes.
Out of Scope Changes check ✅ Passed The changes are limited to TIP key definition, recommendation matching and storage, integration into normal runs, tests, and the required dependency.

unchanged and apply the same best-effort handling to both calls.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Limit prefix removal to supported search operators.

Line 107 removes any scheme-like prefix. For example, mailto:foo@instagram.com becomes foo@instagram.com, then matches Instagram after HTTPS inference. Restrict this pattern to supported query operators and add a no-tip test for non-HTTP URI schemes.
